Type the probability notation for choosing a red disk.
Irina-Kira [14]

The probability notation for choosing a red disk is P(red disk)

<h3>How to determine the notation?</h3>

From the question, we have the following highlights:

  • The scenario represents probability
  • The event is choosing a red flask

Probability notations are represented as:

P(Event)

Since the event is choosing a red flask, the probability would be

P(red disk)

Hence, the probability notation for choosing a red disk is P(red disk)

Suppose x=c1e−t+c2e3tx=c1e−t+c2e3t. Verify that x=c1e−t+c2e3tx=c1e−t+c2e3t is a solution to x′′−2x′−3x=0x′′−2x′−3x=0 by substitu
Harrizon [31]

The correct question is:

Suppose x = c1e^(-t) + c2e^(3t) a solution to x''- 2x - 3x = 0 by substituting it into the differential equation. (Enter the terms in the order given. Enter c1 as c1 and c2 as c2.)

Answer:

x = c1e^(-t) + c2e^(3t)

is a solution to the differential equation

x''- 2x' - 3x = 0

Step-by-step explanation:

We need to verify that

x = c1e^(-t) + c2e^(3t)

is a solution to the differential equation

x''- 2x' - 3x = 0

We differentiate

x = c1e^(-t) + c2e^(3t)

twice in succession, and substitute the values of x, x', and x'' into the differential equation

x''- 2x' - 3x = 0

and see if it is satisfied.

Let us do that.

x = c1e^(-t) + c2e^(3t)

x' = -c1e^(-t) + 3c2e^(3t)

x'' = c1e^(-t) + 9c2e^(3t)

Now,

x''- 2x' - 3x = [c1e^(-t) + 9c2e^(3t)] - 2[-c1e^(-t) + 3c2e^(3t)] - 3[c1e^(-t) + c2e^(3t)]

= (1 + 2 - 3)c1e^(-t) + (9 - 6 - 3)c2e^(3t)

= 0

Therefore, the differential equation is satisfied, and hence, x is a solution.

Need help with this question! Will attach pic! A satellite is to be put into an elliptical orbit around a moon as shown below.Th
Darina [25.2K]
An equation for the ellipse ( standard form ):
x²/a²  +  y²/b² = 1
Here is:  a - semi-major axis and b - semi-minor axis.
Radius of the moon is 1,000 km and the distance from the surface of the moon to the satellite varies from 953 km to 466 km.
a = 1,000 + 953 = 1,953 km
b = 1,000 + 466 = 1,466 km
Answer:
The equation is  x² / 1,953²  + y² / 1,466² = 1
or: x²/3,814,209  +   y²/2,149,156  = 1

In an election, Mr. Jones received 70% of the 1,500 votes cast. How many votes did Mr. Jones receive?
Len [333]
Given situation: Mr. jones received 70% of the 1500 vote casts in an election Question and solution => How many votes did Mr Jones received: => 1 500 is the total number of voters and 70% of it voted Mr. Jones. SO let’s start solving to get the number of voters who voted him. => 70% = 70 / 100 = .70 => 1 500 * .70 => 1 050 , the number of voters who voted him in an election.
